DESCRIPTION AND OPERATION
Safety Belt System
WARNING: All safety belt assemblies include retractors, buckles, front seat belt buckle
support assemblies (slide bar, if so equipped), shoulder belt height adjuster (if equipped), child
safety seat tether bracket assemblies (if equipped) and attaching hardware should be inspected
after any collision. Ford recommends new safety belt assemblies be installed unless a qualified
technician finds the assemblies show no damage and operate correctly. Safety belt assemblies
not in use during a collision should also be inspected and new assemblies installed if either
damage or incorrect operation is noted.
WARNING: Each seating position in the vehicle has a specific safety belt assembly which
consists of one buckle and one tongue. The safety belt assembly is designed to be used as a
pair and is not to be used across seating positions.
A continuous- loop, single retractor active restraint system is used on this vehicle for both the front
seats and the rear seats.
Safety Belt, Lap/Shoulder— Dual Locking Mode
WARNING: Rear- facing infant seats should never be placed in the front seats. Failure to
follow these instructions may result in personal injury.
The dual locking mode retractor on the shoulder belt portion of the combination lap/shoulder safety belt
for the front seat passenger and rear seat outboard passengers operates in two ways:
1. In the vehicle- sensitive (emergency locking) mode, the shoulder belt retractor will allow the
occupant freedom of movement, locking tightly only on hard braking, hard cornering or impacts
of approximately 8 km/h (5 mph) or more. The front and rear outboard safety belt retractors can
also be made to lock by pulling/jerking on the belt.
2. In the automatic locking mode, the shoulder belt retractor locks automatically and remains locked when the combination lap/shoulder safety belt is buckled, restricting occupant
movement. This mode provides tight lap/shoulder belt fit on the occupant and on a child safety
seat or infant carrier installation restraint.
When the combination lap/shoulder belt is unbuckled and allowed to retract completely, the retractor
switches to the vehicle sensitive (emergency) locking mode.
The automatic locking mode must be used when installing a child safety seat on the front passenger
seat and rear outboard seats where dual locking retractors are provided.
Safety Belt Warning System
The safety belt warning indicator illuminates and a chime sounds to remind the occupants to fasten
their safety belts.
The conditions of operation for the safety belt warning indicator and chime are as follows:
zIf the driver safety belt is not buckled before the ignition switch is turned to ON, then the safety
belt warning indicator illuminates for one to two minutes and the warning chime sounds for four
to eight seconds.

If the driver safety belt is buckled while the warning indicator is illuminated and the reminder
chime is sounding, then the safety belt warning indicator and reminder chime turn off.
z If the driver safety belt is buckled before the ignition switch is turned to ON, then the safety belt
warning light will turn on for 3 seconds and then off. The indicator chime will remain off.
Belt Minder (if equipped)
The Belt Minder feature is a supplemental warning to the safety belt warning function. This feature
provides additional reminders to the driver that the driver's safety belt is unbuckled by intermittently
sounding a chime and illuminating the safety belt warning lamp in the instrument cluster.
Safety Belt Extension
A safety belt that is too short even when fully extended can be lengthened. The safety belt extension
(611C22) is available. This assembly will add approximately 20 cm (8 inches) to the length of the
safety belt. Use the safety belt extension only if the safety belt is too short when fully extended. Do not
use the safety belt extension to alter the fit of the shoulder belt across the torso. Safety belt extensions
are available at no cost from any authorized Ford or Lincoln- Mercury dealer.
Lower Anchors and Tethers for Children (LATCH)
The lower anchors and tethers for children (LATCH) system is a standarized and uniform attachment
system for installing child safety seats in passenger vehicles. LATCH- equipped child safety seats have
two lower attachments that connect to the vehicle portion of the LATCH system.
The vehicle portion of the system consists of two attachment points (6- mm wires) bolted to the floor
pan at both second row outboard seating positions. The attachment points protrude from the biteline
between the seat cushion and seat backrest.
If a child safety seat was in use during a collision, inspect the vehicle portion of the system for
damage. If any of the attachment points (6- mm wires) are damaged, a new one must be installed. See
the appropriate removal and installation procedure in this section for service.
Attaching Safety Seats with Tether Straps
Some manufacturers make child safety seats that include a tether strap that goes over the back of the
vehicle seat and attaches to an anchoring point. Other manufacturers offer the tether strap as an
accessory. Contact the manufacturer of the child safety seat for information about ordering a tether
strap. If... Then...

Component Test
Carry out the appropriate Functional Test(s) as determined in Inspection and Verification.
Functional Test I (Buckle and Tongue)
The safety belt buckle and tongue assembly must operate freely during the latching and unlatching
function. Fasten the safety belt by inserting the tongue (male portion) into the buckle (female portion).
1. Verify the following during the latching sequence: zTongue insertion is not hindered by excessive effort.
z A click is heard when the buckle latches the tongue.
2. Verify the system integrity by forcefully pulling on the belt webbing.
3. Unlatch the belt by fully depressing the buckle release button, and allowing the belt to release and retract.
4. Verify the following during the unlatching process: zPush-button depression does not require excessive effort.
z Tongue can be removed easily from the buckle.
5. Repeat the above steps three times.
6. If the inspection reveals an obvious concern(s) that can be readily identified, service as required. Do not attempt to carry out any repair on the buckle and tongue assembly. If a
concern exists with either component, a new safety belt buckle and safety belt and retractor
assembly must be installed.
Functional Test II (Retractor)
The safety belt and retractor assembly must be freely operational for extraction and retraction of the
safety belt webbing between full extension and in- vehicle stowed positions.
1. Extract and retract the safety belt between the full extension and stowed positions.
2. Verify the retractor operates without excessive effort or binding.
3. Install a new safety belt buckle retractor and tongue assembly if no obvious concerns are noticed and the complaint has been verified. z

Functional Test III (System Road Test Inspection)
1. NOTE: If the RH or the rear safety belts are to be tested, the assistance of a passenger is
required.
Fasten the safety belts and proceed to a safe area.
2. Attain a speed of 8 km/h (5 mph).
3. WARNING: The driver and passenger must be prepared to brace themselves if the
retractor does not lock.
Test the safety belts. 1. Grasp the shoulder harness and prepare to lean forward.
2. WARNING: The maximum brake application should be on dry concrete or
equivalent hard surface, NEVER on wet pavement or gravel.
WARNING: The driver and passenger must be prepared to brace themselves
in the event the retractor does not lock.
Make a maximum brake application without a skid.
3. NOTE: Do not jerk on the safety belt webbing when carrying out this test. Lean forward slightly when the brake application is made.
4. The safety belts should lock up with minimum webbing extension.
5. If there is a lockup of both shoulder straps, the safety belt assemblies are functioning correctly. Should either or both retractors fail to lock up at the 8 km/h (5 mph) speed, repeat the test at a
constant 24 km/h (15 mph) speed. (This test must be carried out with the assistance of a RH
front or rear passenger if the RH front or rear safety belts are to be tested).
6. CAUTION: Before installing a new safety belt assembly, inspect the mounting area
for damage and distortion. If the retractor of a new safety belt assembly has been bolted
into a damaged or distorted mounting area, the retractor could be warped and may not
function. If this is the case, remove the retractor and return the sheet metal to the
original configuration and install another complete safety belt assembly.
If the retractors do not lock up at the 24 km/h (15 mph) test, return the vehicle for service of
malfunctioning safety belts.
Functional Test IV (Automatic Locking Retractor) WARNING: After any vehicle collision, the safety belt system at all outboard seating
positions (except driver, which has no "automatic locking retractor" feature) must be checked
by a qualified technician to verify that the "automatic locking" feature for child seats is still
functioning correctly, in addition to other checks for correct safety belt system function. A new
safety belt and retractor assembly must be installed if the safety belt assembly's "automatic
locking retractor" feature or any other safety belt function is not operating correctly when
checked according to the procedures in the workshop manual. Failure to install a new safety
belt and retractor assembly could increase the risk of injury in collisions.
1. Position the seat back into the full up position. Klj . 3 ba
